When the Tropical Rainfall Measuring Mission (TRMM) satellite flew over Tropical Storm Sonca on Friday, Sept. 16 it found moderate rainfall mostly on the southern side of the storm. Chichi Jima can expect some of that rainfall over the weekend as Sonca passes east of the island. TRMM passed over Tropical Storm Sonca and its precipitation radar instrument saw moderate rainfall occurring mostly on the southern side of the storm, while light-to-moderate rainfall was occurring throughout the storm. The southern edge of the storm had rainfall rates between .78 to 1.57 inches ...

Tropical Storm Roke has changed in size and is starting to change in strength. Roke appears to be consolidating in infrared imagery from NASA's Aqua satellite. Roke began its life as a monsoon depression with a large low-level circulation center that over time consolidated and organized. The eastern half of Tropical Storm Roke was seen in an infrared image from NASA's Aqua satellite AIRS (Atmospheric Infrared Sounder) on Sept. 15, and it showed a more consolidated center with strong convection and very cold cloud-top temperatures. Cloud-top temperatures are important ...

Two newer drugs used to treat Type 2 diabetes could be linked to a significantly increased risk of developing pancreatitis and pancreatic cancer, and one could also be linked to an increased risk of thyroid cancer, according to a new UCLA study. Researchers from the Larry L. Hillblom Islet Research Center at UCLA examined the U.S. Food and Drug Administration's database for adverse events reported between 2004 and 2009 among patients using the drugs sitagliptin and exenatide. They found a six-fold increase in the odds ratio for reported cases of pancreatitis with these ...

September 15, 2011 --. In a review of 31 peer-reviewed and published studies, researchers at Columbia University's Mailman School of Public Health looked generational and gender differences in alcohol consumption, alcohol disorders, and mortality. Findings indicate that people born after World War II are more likely to binge drink and develop alcohol use disorders. Researchers also found that the gender gap in alcoholism and problem drinking is narrowing in many countries. Findings will be published in the December 2011 issue of Alcoholism: Clinical & Experimental Research ...

SALT LAKE CITY – New research from the University of Utah in collaboration with the Utah Department of Health (UDOH) shows that the presence or absence of intellectual disability (ID) and autism spectrum disorders (ASD) varies with risk factors such as gender, parental age, maternal ethnicity, and maternal level of education. The study, published Sept. 15, 2011, in Autism Research, also shows that household income level has no association with either ID or ASD, in contrast to what other studies have suggested. ASDs are a group of childhood neurodevelopmental disorders ...

ST. PAUL, Minn. – In a first of its kind study, researchers have found that using two way audio-video telemedicine to deliver stroke care, also known as telestroke, appears to be cost-effective for rural hospitals that don't have an around-the-clock neurologist, or stroke expert, on staff. The research is published in the September 14, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology. "In an era of spiraling health care costs, our findings give critical information to medical policy makers," said Jennifer J. Majersik, MD, MS, ...

VIDEO: Receptors on the cell's surface crowd around the nanotube, effectively standing it upright. The cell mistakes the tube for a sphere and begins to engulf it. Click here for more information. PROVIDENCE, R.I. [Brown University] — It's been long known that asbestos spells trouble for human cells. Scientists have seen cells stabbed with spiky, long asbestos fibers, and the image is gory: Part of the fiber is protruding from the cell, like a quivering arrow that's found ...

Researchers have developed a new method to sequence and analyze the dark matter of life—the genomes of thousands of bacteria species previously beyond scientists' reach, from microorganisms that produce antibiotics and biofuels to microbes living in the human body. Scientists from UC San Diego, the J. Craig Venter Institute and Illumina Inc., published their findings in the Sept. 18 online issue of the journal Nature Biotechnology. The breakthrough will enable researchers to assemble virtually complete genomes from DNA extracted from a single bacterial cell. By contrast, ...

BOULDER -- The planet's deep oceans at times may absorb enough heat to flatten the rate of global warming for periods of as long as a decade even in the midst of longer-term warming, according to a new analysis led by the National Center for Atmospheric Research (NCAR). The study, based on computer simulations of global climate, points to ocean layers deeper than 1,000 feet (300 meters) as the main location of the "missing heat" during periods such as the past decade when global air temperatures showed little trend. The findings also suggest that several more intervals ...

WEST LAFAYETTE, Ind. - The first fluorescence-guided surgery on an ovarian cancer patient was performed using a cancer cell "homing device" and imaging agent created by a Purdue University researcher. The surgery was one of 10 performed as part of the first phase of a clinical trial to evaluate a new technology to aid surgeons in the removal of malignant tissue from ovarian cancer patients. The method illuminates cancer cells to help surgeons identify and remove smaller tumors that could otherwise be missed. Philip Low, the Ralph C. Corely Distinguished Professor of ...

Scientists at the University of Plymouth have shown, for the first time in an animal, that nanoparticles have a detrimental effect on the brain and other parts of the central nervous system. They subjected rainbow trout to titanium oxide nanoparticles which are widely used as a whitening agent in many products including paints, some personal care products, and with applications being considered for the food industry. They found that the particles caused vacuoles (holes) to form in parts of the brain and for nerve cells in the brain to die. Although some effects of nanoparticles ...

Production of crop milk, a secretion from the crops of parent birds, is rare among birds and, apart from pigeons, is only found in flamingos and male emperor penguins. Essential for the growth and development of the young pigeon squab, pigeon 'milk' is produced by both parents from fluid-filled cells lining the crop that are rich in fat and protein. Research published in BioMed Central's open access journal BMC Genomics uses new technology to study the genes and proteins involved in pigeon 'milk' production and shows that pigeon 'milk' contains antioxidants and immune-enhancing ...

Researchers whose findings on the detrimental impact of some common medicines on elderly people were widely reported earlier in the summer have found that taking a few of these medicines does not appear to cause further cognitive impairment in those already suffering from dementia. In a paper published today by the journal Age and Ageing, Dr Chris Fox of the University of East Anglia (UEA) and colleagues from a number of other universities and the NHS describe how they studied a clinically representative sample of 224 people with established Alzheimer's dementia who ...

ITHACA, N.Y. – With an eye toward understanding DNA replication, Cornell researchers have learned how a helicase enzyme works to actually unzip the two strands of DNA. (Nature, online Sept. 18, 2011.) At the heart of many metabolic processes, including DNA replication, are enzymes called helicases. Acting like motors, these proteins travel along one side of double-stranded DNA, prompting the strands to "zip" apart. What had been a mystery was the exact mechanics of this vital biological process – how individual helicase subunits coordinate and physically cause the unzipping ...

Gamers have solved the structure of a retrovirus enzyme whose configuration had stumped scientists for more than a decade. The gamers achieved their discovery by playing Foldit, an online game that allows players to collaborate and compete in predicting the structure of protein molecules. After scientists repeatedly failed to piece together the structure of a protein-cutting enzyme from an AIDS-like virus, they called in the Foldit players. The scientists challenged the gamers to produce an accurate model of the enzyme. They did it in only three weeks. This class ...

TORONTO, ON – Researchers from the University of Toronto (U of T), the King Abdullah University of Science & Technology (KAUST) and Pennsylvania State University (Penn State) have created the most efficient solar cell ever made based on collodial-quatum-dots (CQD). The discovery is reported in the latest issue of Nature Materials. Quantum dots are nanoscale semiconductors that capture light and convert it into an energy source. Because of their small scale, the dots can be sprayed on to flexible surfaces, including plastics. This enables the production of solar cells ...

SALT LAKE CITY, Sept. 19, 2011 – University of Utah engineers who built wireless networks that see through walls now are aiming the technology at a new goal: noninvasively measuring the breathing of surgery patients, adults with sleep apnea and babies at risk of sudden infant death syndrome (SIDS). Because the technique uses off-the-shelf wireless transceivers similar to those used in home computer networks, "the cost of this system will be cheaper than existing methods of monitoring breathing," says Neal Patwari, senior author of a study of the new method and an assistant ...

NEW YORK, N.Y.

The international team, led by Dr Brendan Wintle of the University of Melbourne and the ARC Centre of Excellence for Environmental Decisions, is the first to develop a pioneering decision-support model that incorporates both ecological and economic information to guide conservation investment in the face of climate change. The work is published today [Monday 19 September] in the journal Nature Climate Change. "The ...

In a new study, Chen-Yu Zhang's group at Nanjing university present a rather striking finding that plant miRNAs could make into the host blood and tissues via the route of food-intake. Moreover, once inside the host, they can elicit functions by regulating host "target" genes and thus regulate host physiology. MicroRNAs are a class of 19-24 nucleotide non-coding RNAs that do not code for proteins. MicroRNAs bind to target messenger RNAs to inhibit protein translation. In previous studies, the same group has demonstrated that stable microRNAs (miRNAs) in mammalian serum ...

Researchers from Taiwan have confirmed a bidirectional relation between schizophrenia and epilepsy. The study published today in Epilepsia, a journal of the International League Against Epilepsy (ILAE), reports that patients with epilepsy were nearly 8 times more likely to develop schizophrenia and those with schizophrenia were close to 6 times more likely to develop epilepsy. Prior clinical studies have shown a prevalence of psychosis among epilepsy patients and studies of psychiatric illness have found a strong relationship between schizophrenia and epilepsy, suggesting ...
